Integrated Nutrient Management in Green Gram (Vigna radiata L.) for Enhancing Soil Health

Integrated nutrient management (INM) is a holistic approach that involves the application of organic and inorganic fertilizers to improve soil health and crop productivity. The research study was conducted to demonstrate the effective use of INM on soil health in Green gram. We used a randomized block design (RBD) with four levels of poultry manure @ 0, 50, 75 and 100% ha-1, four levels of nitrogen, phosphorous and potassium@ 0, 50, 75 and 100% ha-1 and rhizobium seed treatment. The revealed that treatment T9 (N20P40K40 kg ha-1 + PM @ 5 t ha-1 and Rhi @ 200g 10 kg-1 Seed) resulted in a slight change in soil pH 6.82, electrical conductivity (EC) 0.198 dS m-1. In post-harvest soil of fertilizers observations showed significant increase in pore space 49.20 %, water holding capacity 47.59 %, organic carbon 0.49 %, and available N 334.23 kg ha-1, P 34.58 kg ha-1, K 202.83 kg ha-1. The increase in NPK was found to be significant (P<0.05) among other treatments in Green gram cultivation and soil quality improvement. The application of N P K with poultry manure was a magnificent source of fertilization.

Growth parameters viz., plant height (90.96 cm), number of nodules plant-1(59.48), number of branches plant-1 (2.66) at 90 DAS (day after sowing), and yield parameters viz., number of clusters plant-1 (14.62), number of pods cluster-1 (13.39), pod length (17.42 cm),pod yield(77.29 q ha-1) has shown best in treatment T12(NPK @100% + PSB @100% + Rhizobium @100%) of cluster bean (Cyamopsis tetragonoloba L.) in comparison to other treatment combination.

Effect of Vermicompost and Neem Cake with Inorganic Fertilizers on Growth and Yield of Maize (Zea mays L.) Var. S2-981

Today, with the advancement of environment pollution and health that is obtained from the improper use of chemical fertilizer, production and use of organic fertilizer is considered as an important approach in the field of soil science in the world’s interest to investors. Research was conducted by using effective management application of vermicompost and neem cake with inorganic fertilizer with objective to enhance the growth and yield of maize crop. It has been concluded from the trial that the different level of vermicompost and neem cake with inorganic fertilizers in the experiment gave the highest value. Effective results were obtained with T9 treatment with combination vermicompost 10 t ha-1, neem cake 500 kg ha-1 with recommended dose of fertilizer NPK 120: 60: 40 kg hhah ha-1. This treatment result shown best plant height with the most leaves, largest stem diameter, longest cob length, heaviest 1000 seed weight, and highest grain yield in compared with the control treatment T1­ had the lowest results in all categories. T9 was found to be the best for the improvement of growth and yield of maize therefore, farmers of Prayagraj region can adopt this combination to give the highest yield of Maize.

Assessment of Physical Properties of Soil from Different Blocks of Coastal Areas, Ganjam District of Odisha, India

An investigation was conducted to analyse the physical properties of soils of different blocks of coastal areas of Ganjam district of Odisha. For this purpose, the soil samples were collected at three depths: 0-15 cm, 15-30 cm, and 30-45 cm, from nine different villages of three different blocks of coastal areas, a total of 27 samples collected and analysed for their physical parameter by using standard Laboratory Technique. The result showed that the Soil Texture of Chatrapur, Rangeilunda, and Chikiti block varied from Sandy loam to Sandy clay loam. The Bulk Density reported 1.31-1.36 Mg m-3, Particle Density reported 2.41 to 2.59 Mg m-3, Specific gravity varied from 2.61 to 2.69, Percent of Pore Space varied 44.56 to 48.13 Percent, Water Retaining Capacity ranged 42.98 to 45.92 Percent. Results suggest that farmers should adopt appropriate soil management techniques, such as crop rotation and conservation tillage, which will contribute to maintain the soil physical characteristics to ensure the sustainability of agricultural practices and the long-term health of the soil.

Influence of Sagarika-Liquid with Inorganic Fertilizers for Enchaning the Soil Health and Yield of Green Gram (Vigna radiata L.)

An experiment was conducted on sagarika-liquid with inorganic fertilizers during Zaid season 2022 at the central research farm of Department of Soil science and Agricultural chemistry, to enhance the productivity. The design applied was 3x3 RBD having three levels of Sagarika-liquid @2ml, 3ml and 4ml L-1 and N P K @ 50, 75and 100%. The result obtained with treatment T9[N P K @100%+ 2 Spray of Sagarika 4ml l-1] that showed vermicompost in combination resulted in a slight change in soil pH at 0-15 cm and 15-30 cm were found 7.12 and 7.27and EC 0.35 and 0.32 dS m-1 respectively. The significant results were in pore space 47.90 and 45.52%, water holding capacity 46.10 and 43.60%, organic carbon 0.54%, 0.44%, and available nitrogen, phosphorus and potassium was found to be significant among other treatments in Green gram cultivation and soil quality improvement. The maximum yield regarding, gave the best results with respect to plant height 45.34 cm, number of pod plant-1 28.16, and number of seed pod-1 8.45. It gave highest yield 1.96 t ha-1. It was also revealed that the application with organic manures was excellent source for fertilization than fertilizers.

Effect of Vermicompost and Zn on Physico-Chemical Properties of Soil in Cultivation of Okra (Abelmoschus esculentus L.) var. Supper Green
